The Preparation of Porous Andalusite Refractory by Foaming Method

Abstract:

Andalusite can be used to produce porous refractory with the method of foaming and its properties are very good. The bulk density can be controlled by the quantity of foam easily. The compressive strength can reach almost 9 Mpa (1.0g/cm³). The expansion transmit by pores, the remianing andalusite and the transverse growing of mullite crystal are all good for the stabilization of sample during heating. The agglomeration of foam is bad for foaming slurry while stiring, so one way to well-distribute the pores is enhancing the strength of foams. Andalusite can prolong the lifetime of refractory.
